IMPROVEMENT IN DLSINTEG-RATJI peci at on f mi g To all whom. itconcern.- l E p Be itknown that I,.D4y1n 0.. EnAUcn, of Charleston, inthe State of South Carolina, hav nv e t in e a u ef lm zoveen D g a ne QMix n Ma h ne of which the following is a specification;

Myinvention relates, to that class of mills which employ twohorizontalrunners, turning in opposite directions, between which thematerialis ground or reduced. r

The object of my invention is to furnish a mill of the above character,in which thematerial will not alone be acted 'uponbythe re e fac t e unnrs, t w as e u d by ing fo c 1 46 Pie e o pa t a ai s e h p e p rt and bd ect percussion from a series of hammers, which new method of grinding,pulverizing, mixing, 0r n grat n consti u es h prime eatu ofinyinvention. r v p I T a ain. s e d c nstru t the a f l the runners ofsaucer shape or depressed form, and of such depth that the material may.be fed to the runners in bulk, and not inva n, e a rdinar y pr c d, Qun other words, form a cavity between the run ners, and provide theiaces, thereof with fur-1 ;when in motion. e I r rows and with hammersor projections, where- The, runners are provided with saucer-shaped bythe material, as it is fedto the rapidly and or depressed faces,preferably deeper at the pp si v v ng u ner s hrown carried bycentrifugal force toward their pe; ripheries, which are brought nearlytogether, or provided with raised rims, the material, in s r see r ound1: ul e ize y the furrows or dress formed on the faces of the runners bythe action of the material against it el r he b ectr lt llssi W ing tothe action of the hammersor projections. My invention further consistsin providing the peripheries of the runners with raised rings or rims,of chilled iron or steel, to retain the material between the runnersuntil ity is ground or reduced snfliciently to. pass through the openingor space left between them. i My invention further consists in thedetails .of construction of'the various parts of the ap- .paratus, whichwill hereinafter specifically be described.

fine to pass between the opening or space left The foot of spindle B isstepped in a lifting of well known construction,

bridge-tree, B which permits of adjustment tocompensate wear, and alsoof flexible adjustment to relieve the step of dead friction.

In Fig. 1, I have shown the respective spindles of the runners as drivenin opposite directions by gearing consisting of bevel-wheels E E,mounted upon the spindles, which mesh with similar wheels F F, mountedon the ends of shafts G G, revolved by any suitable prime mover.

The lifting bridge-tree, in which is stepped the lower end of thespindle B, also carries one end of the shaft G, so that whenever thespindle 'B is adjusted by the lifting bridgetree the shaft G follows itsmovement, owing to its journal-boxes being universal in a wellknown way,whereby the gearing always continues in mesh; butany other mode ofcontinuing the gearing in mesh may be employed.

Thedriving-spindleB is hollow, and leads directly to the cavity betweenthe runners, by

which means I am enabled to feed the material in bulk through a suitabledead-eye suspended directly over and passing through the hollow shaft. o

In Fig. 2,'I have shown a method'of driving the apparatus by belting,which will be readily understood by an inspection of that figure, a

lifting bridge-tree being shown both for the, spindle of the lowerrunner and for the driv ing-shaft H.

In Fig. 4 the runners are shown as provided with false wearing-platesand raised'rings or rims, the hammers being omitted.

In Fig. 5 the hammers are shown as set in the rims and projecting intothe cavity, in-

. stead of being located entirely within the raised rims, as in Fig. 1.I

In F g. 6 the dress or furrows upon the-faces of the runners is omitted,and spikes or projections formed thereon instead, which construction maybe desirable in mixing certain articles, and for other purposes.

In Fig. 7, I have shown runners of an undulatory form, which increasesthe frictional surface, and is adapted for such purposes as cleaning orpolishing materials, and cork or other soft'substance may be inserted inthe peripheries of the runners in lieu; of the steel or hardened rims orrings.

, Various other forms of runners will readily suggest themselves aspeculiarly adapted for particular .materials and purposes to thoseskilled in the art.

The operation of my improved apparatus is as follows: The material isfed through the hollow shaft to the cavity between the runners, whichare rapidly revolved in opposite directions, and, falling upon thedistributing-surface formed upon the center of the lower runner, iscarried by centrifugal force, generated by the rotation of the runners,outward toward their peripheries. The material in its passage is actedupon by the dress or furrows, and, being in bulk, is forced one piece orpart against another piece or part, which greatly aids in its reduction,and when it reaches the hammers or projections the reduction is stillfurther effected by direct percussion. The material is retained betweenthe runners by the raised rings or rims, which form, in reality, saucersof the runners, until reduced, ground, disintegrated, or mixedsufficiently fine to pass between the rims, the facesofwhich may alsoact upon the material before its final exit.

I claim as of my own invention- 1. The saucershaped runner, constructedsubstantially as hereinbefore set forth, having its concave faceprovided with a suitable dress or furrows, with a series of hammers, andwith a raised ring or rim on its periphery.

2. The combination, substantially as hereinbefore set forth, ofhorizontal oppositely-revolvin g concave or saucer-shaped runners, haw

ing raised rims or flanges, and arranged with their concave facesopposite each other, whereby material may be fed in bulk between therunners, and disintegrated by the attrition of one particle uponanother,and by the action of the runners, and retained between them untilsufficiently reduced to pass between the rims.

3. In combination,saucer-shaped horizontal oppositely-revolvin grunners, having their concave faces opposite each other, and beingprovided with furrows,hammers, and raised rims, substantially asdescribed, whereby the mate rial fed to the runners is disintegrated bythe attrition of one particle upon another, by the furrows and hammers,and retained by the rims until thoroughly pulverized.

, 4. The combination, substantially as hereinbefore set forth, ofhorizontal saucer-shaped oppositely-revolvin g runners, the hollow upperspindle through which the feed passes, the lower spindle stepped upon abridge-tree, and the driving-gearing, for the purposes specified. Intestimony whereof I have hereunto subscribed my name. V
